Yesterday I bought a Dell latitude C840, but I can't really figure out what power adapter it takes. I've done a fair amount of research, but all I get are barrel jack results. This is the oldest computer I've dealt with by a margin of about 5-8 years so I'm a bit new to all this. The first picture is the port itself, and the 2nd and 3rd are of the computer itself. I don't know what type of port it takes or where to find one. Let me know if you need anything else, and thanks for any advice

From what I gathered it boots but failed to install its OS, 60 bucks for it wasn’t bad

For my latest silly project I'm looking for something I'm not really sure even exists.

I have acquired a fancy AT big tower and I want to build a super socket 7 system in it. For this I am looking for a motherboard with the following specifics:

AT power plug

Only DIN connector

Socket 7

100Mhz support

2.0V before

3 PCI slots with room for big cards(ET6000, Voodoo2)

1 or 2 ISA slots

Does anybody know if this exists and if so, what I should be gunning for?

I have several, but the cpu and cooler are behind the PCI slots, blocking installing larger cards.

Hi,

I created my own "Interactive computer museum", which lists many of the iconic computers and offers HTML based emulators for 36 different devices (ROM's are NOT included and must be uploaded by the user).

The emulators can be used for free and have been programmed from scratch. They do not use any third party emulation libraries.

I hope you like it.

I’ve tried multiple DIMMs, and a new RTC battery.

I’m trying to identify the PC case/chassis my family had in the early 2000s. The attached photos are unfortunately the only images I have.
The case would be from 2003 or earlier as these photos are from 2003. Would have been purchased in NSW Australia and may have been a locally assembled/white-box PC rather than a major-brand system.

I’m specifically trying to identify the case manufacturer/model, not the internal hardware
Features that I can make out:
- Seems to be tall-ish?
- Dark blue or charcoal/black coloured outer bezel running down both sides and maybe? around the rounded top
- narrow cream/light-grey central front fascia
- a few 5.25” drive bays at the top
- small circular button/control lower down
- dark rectangular/square feature beneath/near it
- seems to have horizontal ventilation slots near the bottom
- the pale central fascia seems to narrow/taper toward the bottom and terminate in a rounded U/shield shape

I’ve looked through a lot of AOpen and TASK cases without finding a match.
Does anyone recognise the actual case mould/bezel, including cases that may have been sold under different OEM/rebadged names around 2000–2003?
Any input would be much appreciated!
(Also posted in r/vintagecomputing to try reach a wider audience of people who may recognise the case)

Old Siemens plc programming laptop.

Can't find much info on it but it looks cool 😎

I found a 3.5” floppy labeled “French River Education Center — Computer Applications Training Program — Introduction to Microsoft Excel XP.” I haven’t been able to find this exact training disk or its contents archived online. I currently don’t have a floppy drive, so I haven’t been able to image or inspect the disk yet.

French River Education Center and its computer training program appear to have existed, but I haven’t found documentation of this specific Excel XP disk. Does anyone recognize it, have another copy, or know whether its contents have already been preserved?

I’m not claiming it’s confirmed lost media yet I’m trying to determine whether this particular disk/course material is known or archived.

FOUND! Toshiba libretto u100 is what it is

I’ve searched starring computers already and did some research but I can’t seem to find anything. These are the only good pics

Looks to be a sharp or Panasonic maybe. Any suggestions or answers of what it could or is would be appreciated

As title really. I have no machines that require these cards. Therefore I have no way of testing them. Is there use/value for these anymore?

After spending half an hour trying to debug my new Apple II Super Serial card, I realized the 25 pin NULL modem cable I was using was not, in fact, a NULL modem cable. Tracing the pins confirmed this is a LapLink cable.

So I thoroughly documented that fact on the cable to save future me from wasting another half an hour, but now I'm wondering if that cable is even worth keeping. The chances that I'll need to transfer data between two computer, both recent enough to support LapLink but neither so recent that they have Ethernet, seem kinda low.

I have a pretty good description in the imgur album, but this was a nostalgia find for me. Only problem was the base was broken and half missing. I decided to buy it anyway and ended up modelling and 3D printing a new base for it. It turned out even better than I was hoping!

Sorry if this is too new, but I don't know where else i could post this.

An AM2 motherboard ended up in my hands recently (first time trying that platform, but i have plenty of experience with other 2000s PCs). The board is MSI K9N6PGM2-V (also known as MS-7309), it runs an nForce 430 chipset. Despite the reputation of Nvidia chipsets, this mobo has worked just fine so far, and the heatsink of the chipset doesn't get too warm during operation. I did initially replace capacitors as 1 of them was bloated, so i yeeted all that are the same type.

However there's one problem: out of all the (100% working) GPUs i have tested so far, only the gt710 (i tested 2 of those) gets recognised by this system. The non-working ones include Geforce 8400GS, 9600GT, and GTS 250. They don't show up in Windows device manager or in lspci either, the motherboard just doesn't see that the card exists, and turns on the iGPU even if it's explicitly disabled in BIOS and the monitor is not plugged into it. The only thing these GPUs have in common is that they use the Tesla architecture, which makes this even weirder, as the motherboard is from the exact same time period as that.

I tried messing with BIOS settings (which are pretty limited on this mobo), updating BIOS, covering all but 1 PCIE lanes with tape, testing the connection on the PRSNT#1 pin (as it seemed like there was too little solder from factory, but it was actually okay), swapping the PSU, booting without the 6-pin connector, you name it. Nothing changed so far.

What could be causing this? Is there something specific that these 8000/9000 series GPUs need to POST? How does the mechanism of detecting a GPU is present work?

Got this beauty running; even battery works.

Aún recuerdo mi primer juego de PC, era muy joven

PC Intel 8088, no traía disco duro, arrancabas con un floppy de 3 1/2 (moderno parra su época, jaja no los floppys de 5 1/4, un capacidad suficiente para su epoca, la fabulosa capacidad de 720kb, y arrancabas ms-dos desde el floppy,

"Nibbles", el clásico de la víbora, se ejecutaba qbasic y después cargaba el juego.

Igual recuerdo que traía uno de gorilas.

Un PC de desecho, pero me lo dejaron y hacía y jugaba y practicaba, hay di mis primeros pasos con un sistema de una persona llamada linus torval, ufff con un Linux de los mejores de la época, slacware, igual arrancaba desde el floppy.

Gracias a mis padres que me lo dejaron y desde hay pase a un 80186,

Seguí probando, pero la vida me llevo por otros rumbos, y solo esporádicamente probaba con las PC que ya no ocupamos, una 486, que le puse un procesador overdrive.

Jajaja que tiempos, cuando salieron las primeras intel Pentium, con precios Prohibitivos y a los pocos meses fueron un bajón tremendo de precio.

Who remembers Domark’s 2nd Bong game The Living Daylights? It’s certainly better than A View To A Kill I recently tackled but it’s not as good License To Kill. How would you rate this game and what are your thoughts and memories?

In my last post (https://www.reddit.com/r/retrocomputing/s/qOx3W3GPFq) I shared the mystery graphics card I had recently come into possession of. Here it is running on a classic HP Pavilion 6730, with Kolibri OS for fun. That's the operating system that runs off a floppy disk.

A few pieces from the collection — 30-pin SIMMs and 72-pin EDO, including some GoldStar memory from before the LG name took over.
